๐Ÿ”€ Wavelength Services

Deterministic Optical Transport for Critical Workloads

Wavelength Services provide dedicated, Layer-1 optical โ€œlambdasโ€ (channels) across a carrierโ€™s Dense Wavelength Division Multiplexing (DWDM) backbone. Unlike shared, routed services, a wavelength gives you fixed bandwidth, predictable latency, and transparent transport between endpointsโ€”ideal for data-center interconnect (DCI), storage replication, AI/HPC fabrics, live media, and low-latency trading.

In the SolveForce Codex, Wavelength sits in ๐ŸŒ Connectivity = Grammar and underpins ๐Ÿ–ง Networks & Data Centers with guaranteed optical paths. See the map โ†’ ๐Ÿ“š SolveForce Codex


๐ŸŽฏ What You Get with Wavelength

  • โšก Fixed, clean bandwidth โ€” common rates: 10 Gb/s, 100 Gb/s, 400 Gb/s (and regionally 800 Gb/s); no oversubscription.
  • โฑ๏ธ Deterministic latency โ€” optical path engineered end-to-end; typical fiber latency โ‰ˆ 5 ฮผs per km (one way) + minimal optical gear overhead.
  • ๐Ÿงญ Transparency โ€” carrier transports your signal at Layer-1; your Layer-2/Layer-3 design stays intact (EPL/OTN/OTU framing available).
  • ๐Ÿ›ก๏ธ Option for Layer-1 encryption โ€” in-flight AES-256 on optical transponders for regulated or sensitive data.
  • ๐Ÿงฐ Choice of protection โ€” unprotected for ultra-low latency, or protected with diverse routes/50 ms optical ring protection.
  • ๐Ÿ“ƒ Strong SLAs โ€” latency, jitter, availability targets; fault isolation down to span/regeneration segments.

๐Ÿ”Ž When to Choose Wavelength vs. Other Connectivity

  • Pick Wavelength when you need:
  • ๐Ÿš€ High throughput + low, stable latency (AI cluster interconnects, SAN replication, market data).
  • ๐Ÿงช Protocol transparency (carry your own Ethernet/FC/InfiniBand framing; avoid MAC/IP changes).
  • ๐Ÿงฉ End-to-end control (you own higher-layer policies; the carrier just moves light).
  • Pick Dark Fiber when:
  • ๐Ÿ”ฌ You want complete optical control (your DWDM, ROADMs, optics) and have ops skillcapex to manage it. โ†’ Dark Fiber
  • Pick Lit Ethernet when:
  • ๐Ÿงฑ You want a managed Layer-2 service (EPL/EVPL) without optical details. โ†’ Lit Fiber
  • Pick MPLS / SD-WAN when:
  • ๐ŸŒ You need any-to-any site connectivity with dynamic routing/policies. โ†’ MPLS โ€ข SD-WAN

๐Ÿงฑ Service Profiles & Interfaces

  • Ethernet Private Line (EPL) โ€” native Ethernet handoff; simple plug-and-play for DCI and L2 domains.
  • Optical Transport Network (OTN) โ€” OTU-framed wavelengths (e.g., OTU2/OTU4) with robust performance monitoring.
  • Common client interfaces โ€” 10GBASE-LR, 100GBASE-LR4/ER4, 400G-ZR/ZR+ coherent pluggables (subject to distance/optics).
  • Fiber type โ€” Single-mode (SMF) G.652D/G.655; connectors typically LC/SC; cross-connects provisioned in colo MMRs. โ†’ Colocation

๐Ÿงญ Design Options (Pick Your Path)

1) Protection & Diversity

  • ๐Ÿ›ค๏ธ Unprotected โ€” fastest, lowest overhead; rely on dual diverse circuits at the design level.
  • โ™ป๏ธ Protected โ€” optical ring or 1+1 path protection; ~50 ms switchover typical; verify exact SLA.
  • ๐Ÿงญ Physically diverse routes โ€” separate laterals, conduits, bridges, and POPs; order route maps/LOAs to confirm separation.

2) Distance Classes

  • ๐Ÿ™๏ธ Metro (โ‰ค 80โ€“120 km): few/no regenerators; minimal latency; perfect for active/active DC pairs.
  • ๐Ÿ—บ๏ธ Regional (โ‰ค 600โ€“1,200 km): add Forward Error Correction (FEC) and occasional regeneration (REG); confirm ROADM add/drop latency.
  • ๐ŸŒŽ Long-haul (1,000+ km): multiple spans with FEC/REG; consider 400G ZR+ vs. transponder shelf for reach vs. power/space tradeoffs.

3) Optical Building Blocks

  • ๐Ÿ”ฆ Transponders / Muxponders โ€” map client lanes into wavelengths; aggregate multiple 10G into a 100G/400G line.
  • ๐ŸŒˆ DWDM Mux/Demux โ€” combine many wavelengths onto one pair; color plan and channel spacing (50/100 GHz).
  • ๐Ÿงฟ ROADM โ€” Reconfigurable Optical Add/Drop Multiplexer; dynamic pathing through the optical mesh; small add/drop latency.

๐Ÿ›ก๏ธ Security & Compliance at Layer-1

  • ๐Ÿ” AES-256 Layer-1 encryption โ€” on transponders/coherent optics; near-zero latency tax vs. higher-layer encryption.
  • ๐Ÿ”’ MACsec/IPsec complement โ€” add Layer-2 MACsec or Layer-3 IPsec where policy requires. โ†’ Encryption
  • ๐Ÿ“‹ Standards compliance โ€” supports HIPAA/PCI DSS/NIST/FedRAMP posture when paired with higher-layer controls.

๐Ÿงฎ Sizing & Performance Planning

  • Throughput โ€” right-size to 100G/400G for DCI/AI; consider 10G for point solutions or backup.
  • Latency budget โ€” fiber path + ROADM + FEC/REG (~ฮผs to low ms); set SLOs by application class:
  • Class A (metro): โ‰ค 2 ms one-way
  • Class B (regional): โ‰ค 15โ€“35 ms
  • Class C (continental): โ‰ค 80โ€“120 ms
  • Jitter โ€” effectively near-zero at Layer-1; validate for synchronous apps (voice/video/market data).
  • Loss โ€” design below 0.1% sustained; monitor optics for dB drift on long spans.

๐Ÿญ Common Use Cases

  • ๐Ÿข Data Center Interconnect (DCI) โ€” stretch L2 domains or run L3 EVPN/VXLAN over deterministic optical paths. โ†’ Networks & Data Centers
  • ๐Ÿ’พ Synchronous Storage Replication โ€” SAN/block replication (SRDF, MetroCluster, etc.) with strict RPO/RTO across metro. โ†’ SAN
  • ๐Ÿค– AI/HPC Fabric โ€” east-west spine bandwidth for GPU pods and training clusters; predictable throughput for NCCL/collectives.
  • ๐Ÿ“ˆ Market Data & Trading โ€” low jitter for feed handlers/matching engines; route diversity for venue resilience.
  • ๐ŸŽฅ Live Media Contribution/Distribution โ€” mezzanine feeds and uncompressed flows over engineered paths; backup via CDN. โ†’ CDN
  • ๐Ÿงช Lab/Research Networks โ€” burst-heavy experiments; transparent framing for custom protocols.

๐Ÿงฐ Hand-Offs & Interoperability

  • ๐Ÿงท Cross-connects โ€” fiber jumpers from your rack to the carrier DWDM panel (colo MMR).
  • ๐Ÿงฉ Client alignment โ€” match client optics (e.g., LR4/ER4) and lane mapping; confirm FEC expectations.
  • ๐Ÿ” L2/L3 overlay choices โ€” EPL for simple L2; or EVPN/VXLAN over routed cores for scale.

๐Ÿ“Š SLAs, Monitoring & Operations

  • ๐Ÿงพ SLA measures โ€” latency, jitter, availability, and time-to-restore defined per route and service class.
  • ๐Ÿ”ญ Telemetry โ€” light levels, FEC counters, symbol errors, BER; integrate with NOC dashboards. โ†’ NOC
  • โ™ป๏ธ Change control โ€” route changes can alter latency; treat fiber work like a database schema change.
  • ๐Ÿงช Testing โ€” RFC 2544/Y.1564 turn-ups; ongoing SLA audits; optical OTDR traces on long spans.

๐Ÿ’ต Commercials & Ordering

  • ๐Ÿ’ธ Pricing model โ€” Monthly Recurring Charge (MRC) per wavelength + Non-Recurring Charges (NRC) for install/cross-connects.
  • ๐Ÿงญ Distance & route โ€” metro vs. regional vs. long-haul affects price, regen count, and protection options.
  • ๐Ÿ—บ๏ธ Diversity paperwork โ€” request route and POP diversity letters; require separate laterals and meet-me rooms if possible.

๐Ÿ› ๏ธ Quick Checklist (Pre-Order)

  1. ๐ŸŽฏ Objective โ€” DCI replication? AI fabric? Trading/market data?
